Grassfed, pastured dairy is higher in Omega3 fatty acids and CLA. What kind of Omega3s are in pastured, grassfed dairy?

to build on this, tropical grass has a lot less ALA than, say, Irish grass, hence wildebeests have a lot less than sheep. And walnuts have a O6/O3 ratio that is anomalous. Palm fruit typically has no O3, and the ratio is infinite. So, way back then when we consumed a lot of fruits and leaves, we also had a large O6/O3 ratio, but a relatively low fat diet. It seems that the O6/O3 requirement is relatively young in evolutionary terms.

Walnuts (rich in ALA) are often found associated with positive effects in observational studies.

And from an evolutionary biology POV, DHA/EPA were rare in the inland tropics where human evolution took place, where they consumed mostly plants and herbivores. DHA/EPA aren't found in high quantities until you get to cold climates and carnivores.

Do you have any information indicating that ALA deserves more credit?

A good fraction of it is ALA, the omega-3 not given enough credit by paleo folks (because it's the plant-sourced omega-3).
